AK5354屬于集成電路（IC）的ADC/DAC-特殊用途。由旭化成微電子株式會社制造生產(chǎn)的AK5354ADC/DAC - 特殊用途該產(chǎn)品族中的產(chǎn)品可用于模擬和數(shù)字表示的信息轉(zhuǎn)換，適用于特定用例，或集成了通用數(shù)據(jù)轉(zhuǎn)換器中不常見的其他功能。例如針對超聲或汽車?yán)走_應(yīng)用集成了低噪聲放大器和可變增益級的器件、注重音頻和視頻的產(chǎn)品、在段碼式顯示器上集成顯示測量值功能的器件、集成輸入輸出電氣隔離的器件等。

FEATURES

The AK5354 is a low voltage 20bit A/D converter for digital audio system. The AK5354 also includes Analog input PGA, therefore is suitable for microphone application and etc. As digital power supply of the AK5354 corresponds to 1.8V, the interface with microprocessor can operate at low voltage. Analog signal input of the AK5354 is single-ended, therefore, any external filters are not required. As the package is 16pin TSSOP, the AK5354 is a suitable for minimizing system.
